No. 823,010. Specification of Letters Patent. Patented June 12, 1906.

Application fi led January 16,1902. Serial No. 90.020.

Be it known that I, CHARLES WELLINGTON ALKER, a citizen of the UnitedStates, and a'residen't of Bridge ort, in the county of Fairfield andState of Connecticut, have invented certain'new and useful Improvementsin- Type-Writing Machines, of which the following is a specification.

My invention relates to type-writing machines, and is directed mainly tothe t ebar action and to the mechanism for shi ting the parts so as-tochange from one case to another in order to print with any one of aplurality of types oneach type-carrier; and the invention is furtherdirected to the typeguide construction for guiding the types inproximity to the printing-point.

y invention consists in certain features of construction andarrangements of parts,- as will be hereinafter described, andparticularly pointed out in the claims.

In the accompanying drawings, wherein verse bar 8, that is secured to anarm 9, pro

ecting from the rock-shaft 10 of the dogrocker 11. The feed-dogs 12 onthe dogrocker cooperate with a feed-wheel 13, which is 0 erativelyconnected to a shaft that exten s through a fixed bearing 14, secured at15 to the top plate 16 of the machine.

The forward end of the shaft referred to is provided with a feed-pinionwith which a feed-rack 18 cooperates. The feed-rack 18 is carried by acarriage 19, that moves upon suitable traverse-rods 20, supported uponthe top plate 16, and the carriage supports a platen 21. ,Each of thekey-levers 3 is conlike reference characters designate correspondingparts in the various views, Figure 1 pivoted at 23 to a bell-crank is avertical sectional view from front to rear of one form of type-writingmachine embodymg my invention. Fig. 2 is an isolated detail I side viewof one of the type-bar actions, the view illustrating one of thelower-case type at theprinting-point. Fig. 3 is a like view of the same,showing the parts shifted to bring one'of the upper-case type to therintin position. Fig. 4is afront viewof t e mac 'ne, with parts brokenaway and others omitted for the purpose of more clearly showing otherparts. Fig. 5 is a detail perspective view of the case-shiftingmechan1sm., Fig. 6 is a detail perspective view of oneof the typebaractuating bell-cranks and hangers emplo ed at thefront of the segment.Fig. 7 is a ive view of another of said bell-cranks and hangers.. Fig. 8is a detail perspective view of one of the bell-cranks and hangers usedat the rear of the segment. Fig. 9 is a like view of another of thebell-cranks and hangers'eim Fig. 10 is an enlarged detail perspectiveView of the ty(peguide. Fig. 11 is an enlarged detail si e viewof aportion of one of the type-bars with one of the side plates removed toclearly show the means for connecting the type holders to the bar. Fig.12 is a'detail front nected to a straight draw-link 22, which is lever24 or24, as the case may be, and the various bellarms are connected atvarious points in the lengths of said bearings. All of the bellcranklevers 24 are-vertically arranged and are pivoted to hangers 25, thatare segmentally arranged and are each apertured at 26 for the receptionof a screw 27, by means of which the bell-cranks 24 and their hangersmay be secured to the front of a vertically disposedfsegment orsegmental support 28. Hangers 29 are secured by screws 30 to the rear.face of the segment 28, and these hangers support the rear set ofbell-crank levers 245' r The hangers 25 and 29 are the same inconstruction and are secured in the same manner to the segment 28,though the hangers upon opposite sides of the segment are staggeredoralternate, as will be seen upon reference to Fig. 4, wherein the frontseries of hangers are each mounted out of alinement with the hangers uon the opposite side of the segment. By t "s arrangement of han ers andbell-cranks a large number of hellcranks may be mounted in acomparatively small space, considered widthwise of the machine, which issubstantially coextensive edge of a type-bar.

- with the width of the keyboard and-without ICC crowding the parts andwithout detracting from the strength thereof by reduc ing the size ofthe parts. From an examination of Figs. 1, 4, 8, and 9 it will be seenthat this staggered arrangement of the hangers and bell-cranks permitsone arm of each of the rear series of bell-cranks 24 to be bent forward,so that it extends between the up right arms of the forward set ofbell-cran 's and may each be connected to a straight draw-link 22, whichin turn is pivoted at 32 to a key-lever, so that while the bell-cranksare upon opposite sides of the segment 28 they all connect with theirkey-levers forward of the segment, and a substantially equal leverage isprovided throughout the various actions. Each of the bell-cranks 24 and2-4 has one arm thereof connected to a draw-link 33, which has its innerend pivoted at 34 to a driving-lever 35. These links may be twisted, asshown in Fig. 4, or may be round links which are screw-threaded at theirends, where they are received in the connecting ends 33, as representedinthe other ligures. Each driver 35 is pivoted at 36 between the ends ofa type-bar proper, 37, which latter is pivoted at 38 to a pivotedguidelink 39, so as to constitute what is known as a jointed type-bar.The upper end of each guide-link is pivoted to a segmental pivotwire 40,secured at 41 to a fixed cross-bar 41. Each driver 35 likewise pivotedat 42 intermediate its ends to a supporting-lever 43, that constitutesone arm of a bell-crank lever which. is pivoted on a segmental wire 44,that is supported by the vertically-disposed segment 45 and is adaptedto move around said pivot-wire in ,aradial slot 46, formed in saidsegment, so that each type-bar proper, 37, swings around fourcentersone, the swinging pivot 38, another,the fixed pivot 40, thethird; the pivot 42 of the driver for the typebar, and the fourth theswinging pivot 36-in the same general'manner as the type-action in theYost machine. The arm 47 of each of the radially and segmentallyarranged bellcranks 43 to 47 is rounded at 48 and projects into theslotted edge 49 of a segmental shift-plate 50. To the shift-plate 50 issecured a bracket 51, which is pivoted at 52 to a lever 53, that ispivoted near its lower end at 5.4 to 'a bracket 55,'that extends fromthe forward face of the fixed segment 45. Extending from the rear faceof this fixed segment is a bracket 57, to which is pivoted. at 58another link 59, that is pivoted at its upper end 60 to a bracket 61,which is secured to the rear face of the shift-segment 50. It will thusbe seen that the segmental shiftlate 50 is mounted and supported uponparallel links 53 and 59 and is adapted to move onsaid links in ahorizontal plane and that unduly this movement of the shift-plate 5Oproduces radial movements of the levers 43. The link 53 varioussupportingis extended downwardly beyond its pivot and is rigidlyconnected to an arm 62, that has its rear end pivoted at 63 to a link64, which in turn is pivoted at 65 to an arm or lever 66, that issecured to a rock-shaft 67. This rock-shaft 67 likewise has arms 67 Xprojecting rearwardly therefrom, the rear end of each of which isprovided with a depending hook or strap 68, that takes around anactuating or shifting lever 69, which is fulcrumed in the same mannerasthe character-key levers and is provided with a finger-key 70 at thekeyboard of the machine. Each of these arms 67 may be connected-at 71 toa spring 7 2, which has its opposite end secured at 73 to a suitablefixed portion of the machine.

From the foregoing understood that a depression of either key 70 willcause the link or arm 53 to be vibrated on its fixed pivot, thus causingthe upper end of the link or arm, together with the segmental shiftlateconnected thereto, to be moved towar the front of the machine. Thismovement of the segmental shift-plate 50 will cause all of thesegmentally and radially arranged bell-crank levers 43 to 47 to bevibrated on their common fixed pivotal wire 44, and thereby move the arm43 of each lever inwardly or radially toward the center of the system,each arm 43 vibrating in the same radial plane that its associatedtypebar moves in and the rear end of each of the links 33 movingor'swinging with its connected arms 35 and 43. The effect of this radialshifting movement of the arms 43 is to change the position of thepivotal center 42 of each type-bar driver, so that when a character-keyis actuated the path of movement followed by the type -bar will bechanged, and the upper-case type will be brought to the rinting-point,as indicated in Fig. 3 of the rawings, though each ty ebar will move atall times in the same ra ial plane, whether for upper or lower caseprinting. In Fig. 3 the dotted line position shows the normal orlower-case printing position of the supporting-lever 43 47, whereasthe-shifted or upper-case position is represented in full lines.

From what has been said it will be understood that the type-bar followsone path of movement in printing a lower-case character and followsanother path of movement in printing an upper-case character, but that,nevertheless, it always moves in the same radialplane.

Referring to Fig. 2, the lower-case type A description it will belIO isrepresented as at the printing-point in full point.

and as above the printing position in full lines, and the dotted lineconnecting the lower-case type inits two extreme positions representssubstantially the path of said type when the parts have been shifted toenable the upper-case type to print, and which upper-case type B isshown as at the printing- It will be observed that the path taken by thelower-case type when the parts are in their shifted ositions isdifferent from and longer than the path of said type when the parts arein their non-shifted positions. Simiarly the upper-case type travelsthrough different paths and paths of different lengths when the partsare respectively in normal and shifted positions; but these varyingpaths of the upper-case type are not shown by dotted lines in order tosimplify the views and avoid confusion.

Normally the shift-plate 50 bears against and is stopped by the rear nut50 but when shifted said plate strikes against and is arrested by theforward nut 50*. These nuts are adjustable on threaded rod 50, whichpasses freel through the shifter-plate and is supported by bracket 50attached to the cross-bar 41.

From an inspection of Fig. 4 it will be seen that the various type-bars,drivers, and supports 43 are mounted in planes that radiatesubstantially from the point indicated by the letter at in said figureand that in the operation of the machine the type-bars and drivers (andwhich drivers may .be considered as parts of the type-bars) movein'these same planes both when the parts are in the normal position andwhen in the shifted position. The supports 43, which effect thec rangeof case, likewise move in the same radial planes in which the typeba'rsmove.

From a comparison of Figs. 1 and 4 it will be observed that the pointit, heretofore referred to, isin the same horizontal plane with theprinting-point and the axis of the platen, as is indicated by the dottedline a in Fig. 1. By reason of the above features of construction I amenabled to make all of the typebars without lateral bends at the typeends of the bars and to arrange the types one behind the other in theplanes of the type-bars and with the printing-faces of all of the typesat right angles to said planes. Straight typebars or those withoutlateral bends and wherein every portion of'the type-bar moves in asingle plane and those wherein the )rinting-faces of the types are atright angles to vsaid plane throughout the system have many advantagesover type-bars having lateral bends where the types are placed and overstraight bars where the types are offset or overhang and over type-barswherein the printing-faces of the types are at angles other than rightangles to the plane of movement of the bar which carries said types andare at varying angles throughout the system.

In prior machines it has alwa s been customary, as far as my knowle geextends, either to bend the outer type ends of the bars more and more asthey approach the sides of the segment or circle, where each type-bar isto be provided with a plurality of types, as upper andlower case types,or else to make the type-bars strai ht from end to end and place the uper and lower case types thereon at gradual y-increasing angles, workingfrom the middle of the machine outwardly in both directions or to havethe pr ntingfaces of the types at different angles throughout the systemrelatively to the planes of movement of the type-bars. It results fromthese constructions last described that the types are oflset from oroverhang the major axis of the t pe-bar and not only take up more roomin the basket as the sides of the machine are approached, but suchtype-bars print with a crank-like action and produce faulty andobjectionable impressions or that the. faces of the types will strikethe platen in a plane other than at right angles to the plane ofmovement of the type-bar, and a faulty impression will result.

In my construction it will be observed tha t there are no lateral bendsin the type-ha rs at any part of the segment and that no one of thetypes on any of the hers is offset from or overhangs its bar. The typesbeing arranged one behind the other and in the plane of the bar eachtype will be supported by the body of the bar itself during the impactof the type, and the hitherto offset or crank impressions are thusavoided. The faces of all of the types meeting the platen at rightangles to t is planes of movement of the type-bars prevent blurringimpressions. Moreover, I am enabled by my construction to provide agreater number of type-bars in a given space than any other machinewherein there are a plurality of types on a bar and wherein the typesare offset from the main body of the It will be understood that byreason of the fact that the types are arranged one'behind the other, asexplained, and that in the shifting of the parts for upper and lowercase printing the parts all move in radial lines, I may provideanindefinitenumber of types on each type-bar, adding, of course, thenecessary nunfber of shift-keys for the different. number ofshil'tsrequired-that is to say, each type-bar may have three or more types andmay have two or more shil'ts accordingly. Upon reference to Figs. 1 land 12 it will be seen that each elongated type-holder 74 is pivoted at75 between the side plates T6 of each type-bar 37 and that eachtype-holder i 18 provided with an elongated opening 77, 1 through whicha pin 78, secured to plates 7c,

- type.

extends. Each type-holder has atapering recess at 74: for the receptionof a tapering stem 74", which projects from a type-body 74", so thateach type-body may be turned, with its stem, to properly position theface of the type on its holder. The pin-and-slot connection between eachtype-holder and its type-bar adapts'the type-holder to move on its pivotindependently of the movement of the type-bar. This independent movementof the type-holder on its bar answers a twofold purpose in the presentinstance. It enablesthe type to be properly centered in the type-guidein the movement of the type to the printing-point, and it likewiseenables the face of the type to be maintained properly positioned on thefixed segmental inking-pad 79, whether the parts be in the normal position to write lower-case characters or be shifted. to write upper-casecharacters. In other words, the slight movement which is imparted to thevarious type-bars 37 by an operation of the shift key is ineffective todisplace the face of the type from the inkingad by reason of thisindependent movement of the type-holders and their type bars orcarriers. that the invention is not restricted to the use of types whichmove with relation to their type bars orcarriers and that thecase-shifting mechanism may be employed in connection with type-barswherein the types or their holders are fixed to the bars. Also theinvention is not limited to jointed type-bars. While it is one of the obects of the invention to produce a front-strike machine in which thetypes are inked by a pad and print directly on the paper without theinterposition of the usual inking-ribbon, nevertheless some features ofthe invention may be embodied in machines wherein an inkin -ribbon isemployed instead of'an inking-pas Situated adjacent to theprinting-point is a type-guide 80, whose bracket or support 8O issecured at 81 to a fixed portion of the machine. The support or bracketof this type-guide is bent at 82 to provide a clearance for theupper-case-type holders, elongated stems or supports when thelower-casetype holders or stems are within the guide, as indicated inFig. 2, and the bracket 80 is secured to the rear portion of the guidein order not to interfere with the type outside of the guide. Thetype-holders, elongated It should be understood, however,

stems, or type-supports 74 on each type-bar are arranged at suchdistance'apart as to leave sufficient space between them to permiteither type to pass outside the guide when the other type passes throughthe uide in its movement to t e printing-point, tire walls of the guidebeing of less thickness than the space between the stems or supports ofeach The body of this typeuide 80is substantiall cylindrical exterioflyand-is provided with inner guiding-faces 83, that are wider than thearms seaoio adapted to surround the type-body upon all sides. faces, sothat the internal opening is rectangular in crosssection to cooperatewith four faces'83 (see Figs. 11 and 12) on each typebody to properlyguide the type to the print ing-point and to properly center it in thetype-guide. The faces 83 are inclined in the usual manner toward thetype-opening 84 and are, in effect, angular walls of the guideopeningwhich surround u on all sides the anular sides of the type-b0 y. Theupper-leftl iand corner of this type-guide is cut away at 85, and thiscorner of the guide is preferably beveled on the outside toward the rearthereof, so that the operatorrnayexamine the lastwritten characterwithout moving the platen to either side of the type-guide. it will beun derstood that it is preferable to cut away the upper left-hand cornerof the type-guide, hecause of the fact that the opening 85 will thusbe-provided at that side of the guide toward which the platen moves inits usual letterspace-feed movement. By reason of the generalcylindrical contour of the outer face of the type-guide it enables afree space to be provided at every point around the guide for thetype-holders which are not carried to the printing-point during theactuation of the keys, but which must be maintained either above orbelow the type-guide or to either side thereof when various bars arebrought successively to the printing position. Thus when one of the keysat the-center of the key- ,board is actuated to print a lower-casecharacter then the other type and itsholder or stem on the sametype-barwill take a position below the guide, as represented in Fig. 2of the drawings, whereas when one of the-same keys is actuated to printan upper-case character the other type and its holder or stem-on the barextends above the type-guide, as represented in F i 3 of the drawings Itfollows that the thic ness of each wall of the guide is such that itwill permit the types or their stems to straddle the uide at everypomtthat is to say, the thickness of the walls of the guide is such thatthey are adapted' toextend between the types, so that one type ona barmay be outside the guide when theother type on the same bar is withinthe-guide and at the printing-point.

It will also be seen bycomparison of these levers in Fig. 4 that the arms of the differentlevers-connect with the bearings 24* thereof at different points intheir widths.

tances apart, though the distances between the arms of the variouslevers may vary.

Thus upon reference to Fig. 4 it will be seen.

that the arms of the levers 24 and 24* are spaced farthest apart at thecenter of the segment and the spaces between them gradually decrease aseither side of the segment is This facilitates the connection betweenthe various levers and their drivers and lgey-lev erswithout thenecessity of providin an irregular mounting of the hangers. It willikewise be seen that the upright arms of the levers 24 and 24 arearallel throughout the segment, those at the extreme sides being bentinwardly at their upper ends to 1facilitate the connection with theirassociated .in 's.
